Similar words in Passage
Q9-10. They do this by seeking to blame their _______for the fact that they are overweight and erroneously believe that they use _________energy than thin people to stay alive
…obese people have often sought solace in the excuse that they have a slow metabolism,
From the question, we can assume that the answer for Q9 may be a noun.
“Seeking to blame” and “sought solace in the excuse” have the same meaning in this context.
“They (obese people) have a slow metabolism”. Depend on using words from box, the correct answer for Q9 should be “metabolism”.
“Slow metabolism” refers to “using less energy than thin people”.
Thus, the correct answer for Q10 should be “less”

Q11. However, recent research has shown that a _________problem can be responsible for obesity…
O'Rahilly's groundbreaking work in Cambridge has proven that obesity can be caused by our genes. 'These people are not weak- willed, slothful or lazy,' says Prof. O'Rahilly, 'They have a medical condition due to a genetic defect and that causes them to be obese.'
From the question, we can assume that the answer for Q11 may be an adjective.
“due to a genetic defect and that (genetic defect) causes them to be obese” means that “genetic problem can be responsible for obesity”
“Responsible for obesity” and “due to sth, causes to be obese” have same meaning in this case.
Thus, the correct answer for Q11 should be “genetic”
- 12 Answer: consume

Q12. as some people seem programmed to _______more than others
while major genetic defects may be rare, many people probably have minor genetic variations that combine to dictate weight and are responsible for things such as how much we eat, the amount of exercise we do and the amount of energy we need
After reading Paragraph E, we can assume that the answer for Q12 may be a verb.
“Programmed” and “combine to dictate” have the same meaning in this context.
“How much we eat, the amount of exercise we do and the amount of energy we need” refers to “consume energy”.
Follow the words are recommended, the correct answer for Q12 should be “consume”

Q13. The new research points to a shift from trying to change people’s ________ to seeking an answer to the problem in the laboratory
Until recently, research and treatment for obesity had concentrated on behaviour modification, drugs to decrease appetite and surgery.

“Point to” and “concentrate on” have same meaning in this context
“Change” and “modification” have same meaning in this context.
Using words recommended, the correct answer for Q13 should be “behavior”
Weight, exercise, sleep, mind, bodies, metabolism, less, more, behavior, physical, use, mental, consume, genetic.
READING PASSAGE 1
You should spend about 20 minutes on Questions 1-13. which are based on Reading Passage 1 below.
Tackling Obesity in the Western World
A - Shifting the blame
Obesity is a huge problem in many Western countries and one which now attracts considerable medical interest as researchers take up the challenge to find a 'cure' for the common condition of being seriously overweight. However, rather than take responsibility for their weight, obese people have often sought solace in the excuse that they have a slow metabolism, a genetic hiccup which sentences more than half the Australian population (63% of men and 47% of women) to a life of battling with their weight. The argument goes like this: it doesn't matter how little they eat, they gain weight because their bodies break down food and turn it into energy more slowly than those with a so-called normal metabolic rate.
B - Expert explains energy requirements of obese people
'This is nonsense,' says Dr Susan Jebb from the Dunn Nutrition Unit at Cambridge in England. Despite the persistence of this metabolism myth, science has known for several years that the exact opposite is in fact true. Fat people have faster metabolisms than thin people. 'What is very clear,' says Dr Jebb, 'is that overweight people actually burn off more energy. They have more cells, bigger hearts, bigger lungs and they all need more energy just to keep going.'
C - Proof of the truth
It took only one night, spent in a sealed room at the Dunn Unit to disabuse one of their patients of the beliefs of a lifetime: her metabolism was fast, not slow. By sealing the room and measuring the exact amount of oxygen she used, researchers were able to show her that her metabolism was not the culprit. It wasn't the answer she expected and probably not the one she wanted but she took the news philosophically.
D - New perspective on the horizon
Although the metabolism myth has been completely disproved, science has far from discounted our genes as responsible for making us whatever weight we are, fat or thin. One of the world's leading obesity researchers, geneticist Professor Stephen O'Rahilly, goes so far as to say we are on the threshold of a complete change in the way we view not only morbid obesity, but also everyday overweight. Prof. O'Rahilly's groundbreaking work in Cambridge has proven that obesity can be caused by our genes. 'These people are not weak- willed, slothful or lazy,' says Prof. O'Rahilly, 'They have a medical condition due to a genetic defect and that causes them to be obese.'
E - Lifestyle change required despite new findings
In Australia, the University of Sydney's Professor Ian Caterson says while major genetic defects may be rare, many people probably have minor genetic variations that combine to dictate weight and are responsible for things such as how much we eat, the amount of exercise we do and the amount of energy we need. When you add up all these little variations, the result is that some people are genetically predisposed to putting on weight. He says while the fast/slow metabolism debate may have been settled, that doesn't mean some other subtle change in the metabolism gene won't be found in overweight people. He is confident that science will, eventually, be able to 'cure' some forms of obesity but the only effective way for the vast majority of overweight and obese people to lose weight is a change of diet and an increase in exercise.
F - Hidden dangers
Despite the $500 million a year Australians spend trying to lose weight and the $830 million it costs the community in health care, obesity is at epidemic proportions here, as it is in all Western nations. Until recently, research and treatment for obesity had concentrated on behaviour modification, drugs to decrease appetite and surgery. How the drugs worked was often not understood and many caused severe side effects and even death in some patients. Surgery for obesity has also claimed many lives.
G - Rodent research leads the way
It has long been known that a part of the brain called the hypothalamus is responsible for regulating hunger, among other things. But it wasn't until 1994 that Professor Jeffery Friedman from Rockerfeller University in the US sent science in a new direction by studying an obese mouse. Prof. Friedman found that unlike its thin brothers, the fat mouse did not produce a hitherto unknown hormone called leptin. Manufactured by the fat cells, leptin acts as a messenger, sending signals to the hypothalamus to turn off the appetite. Previously, the fat cells were thought to be responsible simply for storing fat. Prof. Friedman gave the fat mouse leptin and it lost 30% of its body weight in two weeks.
H - A very uncommon complaint
On the other side of the Atlantic, Prof. O'Rahilly read about this research with great excitement. For many months two blood samples had lain in the bottom of his freezer, taken from two extremely obese young cousins. He hired a doctor to develop a test for leptin in human blood, which eventually resulted in the discovery that neither of the children's blood contained the hormone. When one cousin was given leptin, she lost a stone in weight and Prof. O'Rahilly made medical history. Here was the first proof that a genetic defect could cause obesity in humans. But leptin deficiency turned out to be an extremely rare condition and there is a lot more research to be done before the 'magic' cure for obesity is ever found.
